Siphon starter and automatic shut-off



Patented Apr. 5, 1927.

JOHN Morin, or DETROIT; Mronreiliivl srriioiv s'rAa'rnaann AUTOMATIC sirUT-.oijrf Applicationled April 28, 1924. Serial No. 709,375.

This invention relates toa siphon starter Vand automatic sluit olf, and my invention aims to provide a pump adapted to raise liquid for continuous flow, and sluit -offtlie flow of liquid from the supply-.receptacle incident to changing from one receiving receptacle to another. rlhe pump includes -a novel arrangement of a cylinder, tubular piston rod and piston, each reciprocable relative to one another, with the piston serving as a valvular mean-s for controlling the discharge of liquid by the pump. y

A siphon starter in accordance with this invention may be advantageously used when racking off beverages, that is, lilling small containers from a large vessel, and as a further instance I may mention the transfer of fu'el from an automobile tank to a carbureter or other tank. ln fact my pump may be used in places where a siphonic action is required for the transfer of liquid, and by embodying the valvular fea-ture in the pump, the transfer and control of liquid may be expeditiously and economically performed.- l i The liquid transferring means will be hereinafter specifically described and then claimed, and reference will now be had to the drawing, wherein- Figure 1 is a longitudinal sectional view of the siphon starter showing it in position to establish communication between a supply receptacle and a receiving receptacle, an

Fig. 2 is an enlarged longitudinal sec-f tional View of the siphon starter showingr the piston thereof serving as a valve to temporarily shut olf the flow of liquid.

In the drawing, 1 denotes a supply receptacle, as a barrel having its head provided with' an opening 3 and extending through said opening in proximity to the bottom of the barrel is a flexible conduit 4. The liquid within the receptacle 1 is adapted to be withdrawn through the conduit 4 and placed in a receiving receptacle A5, for instance a bottle. To start the liquid flowing through the conduit 4 I provideva novel pump to induce a siphonic action, and the pump is also` designed so that the flow of liquid may be temporarily shut oil', without necessarily destroying` the siphonio action, so that an kempty receptacle may be substituted for a filled receptacle.

The pump comprises a cylinder 6 having a fixed endl cap 7 provided with a nipple @Faces 8 over which nia-y be fitted. the end dof the I conduit 4. The opposite end of the cylinder 6 is provided withv a detachable cap` `Shaving a tubular 'guide 10V for a tubular yor'hollow piston rod 11, which has its v-outer end provided with the head or peripheral lflange 12 and a discharge nippple 13.` Thexheiid 12 may support thepump on the mouth of the' receptacle 5 with the' discharge :nipple 14 extending into the neck of the receptacle, and with the head 12 simply resting on the receptacle mouth, without being sealed, air may escape from the receptacle 5 as it is lled with liquid. A n

The inner end of the tubular piston rod Lv11 is reduced and formed with an annular shoulder 14. and mounted on the inner end of the piston rod isl an abutment 15, pref.

erably in the form of a screw, and a resilient seat member 16. The tubular piston rod 11 y has a lateral port 17 in proximity to theV seat member 176 adapted to establish communication between the cylinder -6 and the',`

tubular piston rod 111. v

Shiftable on the reduced end of the tubular piston rod 11 and adapted to engage n either the shoulder 14 or the seat member v 1G, as a piston, comprising a flanged `sleeve 18 provided with a cupped piston `ring 19,v

sembled on the sleeve 18. The sleeve 18y serves the function Aof a valve when in engagement with the seat member 16, because it closes the port 17.

By rapidly reciprocating the cylindery 6, on the tubular pistonrod 11, the liquid in the` receptacle 1 can be lifted to flow through the conduit 4 into the upper end of the cylinder 6 and through the port 17 and the tubular piston rod 11 into the receiving receptacle 5. When the cylinder 6 is raised, as shown in Fig. 2, theport 17 can be closed to maintain a head of liquid in the conduit 4, while the pump is being transferred from a filled receptacle to an empty receptacle. rlhere is always a suflicient head of liquid in the conduit, 4 to continue the siphonic action when the cylinder 6 is open to the port 17, and by embodying the valve in the pump, it Obviates squeezing the conduit 4 or using, any other valvular means to temporarily shut off the flow of liquid.

It is obvious that mv pump may be ad- VVantagfeously4 usedfv when making lionie WAL siphon starter and 1 comprising asl tubularpiston rod` having` a madehevemges and.A bottling the saine,V and Wlnlein the drawing there is'illustrated a referred enibodiinentof niy invention, ity v1s to'be understood that the structural elenents are suseeptibleto such Var-iationsvand modifications as fall Within the scope of the appended claim. y f
